Parallel Processing in EMAN2

EMAN2 uses a modular strategy for running commands in parallel. That is, you can choose different ways to run EMAN2 programs in parallel, depending on your environment. Unfortunately, as of May, 2009, the parallelism infrastructure is just beginning to come together. This should be gradually fleshed out over summer 2009. At the moment, only one parallelism infrastructure is fully functional.
